Specification of Letters Patent.

Application filed May 1, 1912. Serial No. 694,593.

To all whom it may concern: I

Be known that I, GEORGE E. MnNsoN, a citizen of the United States, residing in the city and county of Providence, in the State of Rhode Island, have invented a new and useful Pin-Tongue, of which the following is a specification.

The purpose of my invention is to pro vide an inexpensive, one-piece. pin-tongue eiiiciently usable with a pinch-joint or any form of hinge-joint for pins, brooches and the like, and which is provided with means integral with itself for limiting the movement or pivotal travel of the pintongue, and for imparting the requisite tension to the pin-tongue.

To this end my invention consists in the novel construction, combination and arrangement of parts described herein and shown in the accompanying drawing, in which: i v

Figure 1 is a perspective view showing my pin-tongue applied to a pin. Fig. 2 is a plan view of my pin-tongue blank. Fig.

3 is an elevation of my pin-tongue ready for insertion in the pin joint. Fig. i is a side elevation, a portion'of the pin-tongue be- 111g broken away, and the hinge joint shown in dotted lines. Fig. 5 is a similar view showing the pin-tongue in its opened position. Fig. 6 is an edge view of the assembled pin, hinge joint and pin-tongue, with the latter in its closed position, as in Fig. 1.

Similar reference letters and numerals indicate like parts in the several figures.

In the accompanying drawings, 1 represents my newly invented pin-tongue struck out from a fiat strip of metal, with an integral longitudinal extension 2, an integral lateral straight extension 3, and a curved lateral extension 4 also integral with said pin body 1, which is fiat as are the several named extensions. (Fig. 2.) This blank is then swaged and the extension 3 brought in toward the free end of the extens1on t to form a slot between the two, and a semicircular recess 5 at one side of said slot, adapted to receivethe pivot pin of a hinge joint, or to engage the pivot ears of a pinch-joint, as the casemay be. At the same operation the free ends of the extensions 3 and 4: are turned practically at right angles to the faceot the pin body 1 to form laterally extending stops 2 3 on opposite sides of said recess 5. (Fig. 8.) Said stop Patented Mar. regrets; Y

and are thereby adapted to serve as here inafter explained. tongue is thendrawn down and pointed-at one end, (Fig. 3), thereby forming a rr iun d, pin-tongue from asingle piece of flat metalg In the practical operation of my invens tion, the pin-tongue, being struck out oft-a piece of fiat metal with the integral latterally directed stops, and the open slot with the semicircular pivot recess disposed at one side of said slot, and the pin-body drawn into cylindrical shape and pointed at one end, the slotted end of the pin-tongue is inserted between the joint members 8 of a pin and the pivot pin inserted through said The body off the pin-. I

joint members and the interposed pivot recess 5, with the lateral stop 3 at one side of said joint member, and the lateral stop 2 at the opposite side of such joint member. \Vhen the pin-tongue is closed to engage the keeper 6 of the pin 7, the stop 2 will be brought into contact with the rear edge of the joint member near the top of said member, and will thereby serve both to impart increased tension to the spring-tongue, and to resist any tendency-of the curved extension 4 to open up, ors-pread away from the extension 3. When the pin-tongue is turned upward upon its pivot to open the pin the stop 3 will be brought into contact with the front edge of the hingemember near its top and thereby limit-the movement of the pin-tongue in that direction, at the same time serving to prevent the extension 3 from being separated from the free end of the extension 4. Thus the stops 2 and 3 serve to keep the pin-tongue at all times in the proper loose connection with the pivot pin. In case the pin-tongue is to be used in connection with a pinch-joint, (that is, a joint in which laterally projecting lugs serve in place of the ordinary pivot pin,) my pin-tongue is inserted between the hinge members which are then pinched together to bring the pivot lugs into engagement with the pivot recess 5.

It is to be noted as an importantfeature and advantage of my invention, that by reason of the construction-form and mode of operation of my pin-tongue I am enabledto impart the requisite spring tension to the pin-tongue and also to secure proper limitamasses without adding to or building up either the hinge member or the body of the pin beneath the hinge member.

I, elaim 1. A pin tongue struck from a fiat strip ef netal, and comprising a cylindrical body pointed at one end, and provided at its free end with an integral longitudinal extension having its free end turned angularly to form a stop disposed above the pintle recess, a curved extension integral and projecting angularly from said longitudinal extension in the plane thereof, and provided with a recess in its inner edge adapted to receive a pintle, and an extension integral with and projecting angularly from said pin body and spaced a distance forward of said curved extension in the plane of the latter, and

having its free end angularly turned to form a stop disposed below said pintle recess.

its pivot engaging end with a longitudinal prolongationterminating in an angularly directed stop disposed. above the pivot recess, an integral extension disposed substantially at right angles to said prolongation in the plane thereof, and terminating in an angularly directed stop disposed below said pivot recess, and an integral curved extension disposed between said prolongation and first mentioned extension in their common plane, and provided with a recess in its inner edge adapted to loosely engage said pivot.
